On Sunday, February 22, thousands of people will tune into their televisions for one of the most exciting evenings of the year: The Academy Awards!

It’s Hollywood’s biggest night; the most prestigious award show of its kind.

And of course, all the stars will be sauntering down the red carpet looking their absolute best.

As a physician, I can tell you: those magnificent red carpet looks that cause viewers to hang their jaws on the floor with amazement… don’t just “happen.” There’s a tremendous amount of work that goes into creating that kind of ultra-glam, camera-ready appearance.

Here are just a FEW of the steps that your favorite stars are taking to achieve that level of glamour:

HAIR. Deep conditioning for weeks leading up to the event.

Stylist Adir Abergel, whose clients include Rooney Mara and Eva Green, gives her clients a series of deep-conditioning hair masks to apply — and sleep in — during the weeks leading up to that big red carpet moment. This ensures ultra-glossy locks that gleam under the bright lights!

Celeb trainer Valerie Waters puts each client on a customized, high-intensity program for at least six weeks leading up to the event, focusing strongly on whichever body-zone is going to be exposed in her client’s gorgeous gown.

To soothe those sore muscles and keep stress hormones (which can cause weight gain) levels down, some trainers insist upon their clients getting a DAILY massage, especially the week of the big event. At least this part sounds good to me!

NUTRITION. A super lean & clean meal plan.

While some celebrities are infamous for their wild drop-weight-fast detoxes and diets, most of the top celebrity trainers advocate a more “common sense” approach. (After all: their clients are training like athletes. They need high-quality fuel!)

Nutritionist Heather Bauer, who works with stars like Tyra Banks, encourages her clients to cut out processed foods, white sugar, white bread, and artificial sweeteners that lead to gas and bloating (like diet soda and sugar-free gum).

Bauer also recommends drinking two liters of water every day, minimum. (No flavoring or sweeteners. Straight up H20!)

Rachel Beller, author of Eat to Lose, Eat to Win, recommends sipping fennel tea for the five days leading up to the event (it’s reported to have de-bloating properties).

On the actual day of the event? Nutritionist to the stars Haylie Pomroy tells her clients to keep high-protein snacks, like turkey jerky, hidden away in their diamond-encrusted clutch bags to prevent a “hunger crash” during the long awards ceremony.

BUT… That’s just the beginning.

As if six weeks (or more!) of grueling preparation, highly-disciplined eating and Olympic-level training isn’t enough… there’s still more work to be done.
